MulClip activation function boosts microcontroller AI performance

By PulseAugur Editorial · [1 sources] ·

Researchers have developed MulClip, a novel activation function designed for reservoir computing on microcontrollers. This function significantly speeds up state-update times compared to traditional tanh functions, achieving 0.34 times the speed on an ARM Cortex-M4. MulClip's design allows for both monotonic and non-monotonic folding regimes within a single function, enhancing expressiveness. Evaluations showed MulClip achieving a 22% lower NMSE on the NARMA-20 task and improving accuracy on 8-bit parity tasks to 0.97-0.98. AI

IMPACT Enables more efficient AI processing on resource-constrained microcontrollers.

    MulClip: A table-free activation function with monotonic and folding regimes for reservoir computing on microcontrollers

    This letter proposes MulClip, a lightweight activation function for reservoir computing (RC) on microcontrollers (MCUs). In a ring reservoir, a representative sparse RC topology, multiply-accumulate operations are few, and evaluating tanh accounted for 75% of the state-update tim…
